Given numbers are 154,818,898,661

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 154,818,898,661 is 18693551954.

Find LCM of 154,818,898,661 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 77 x 409 x 449 x 661 = 18693551954

Therefore, the lowest common multiple of 154,818,898,661 is 18693551954.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

154 x 818 x 898 x 661 = 74774207816

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

154 : 1, 2, 7, 11, 14, 22, 77, 154

818 : 1, 2, 409, 818

898 : 1, 2, 449, 898

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,818,898,661, is 1.

Now, the common factors can be found like this.

154:2x 7x 11

818:2x 409

898:2x 449

661:661

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 74774207816/(1x4)

LCM = 74774207816/4

LCM = 18693551954

Thus, we can understand that the LCM of 154,818,898,661 is 18693551954.
